The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit
replaces the existing io/ioutil functions with their new definitions in
io and os packages.

This plugin is mostly compatible with the nginx plugin, but runs the proxy within a docker container. Users do not have direct access to add custom openresty configuration at this time, but instead receive the ability to setup automatic ssl on first request via letsencrypt integration.
This increases the time to list apps from .05s to .2s~.3s on the simplest check, but the increased time is worth it for actually verifyng access to an app (should that need arise).
We'll also want to add the same to app existence checks.
Trace mode is useful for shell code, but less so for golang. Adding debug logging in golang for trigger calls makes it a little easier to see what is happening.
Previously, this could get a bit hazy when running the command within a goroutine. The new method creates pipes for writing stdout/stderr for each call to PluginTriggerOutput, then debug logs if if trace mode is on.
While it is a bit weird to read, it is more correct and should get rid of any parallel processing issues.
The previous output would also include a message like `exit status 1`. This allows us to silence that output and instead only capture that which was return from the subprocess.
